Mighty, elemental forces molded North America – fiery eruptions, titanic floods, the grinding of great ice sheets and massive impacts from space all shaped our homeland. The epic three-part series unfolds in a forgotten world that existed long before our own, crossed by lost mountain ranges, giant deserts and vast inland seas.
Join Ann Curry for the reunions of people whose lives crossed during the deadly eruption. Mindy searches for a scientist’s family to tell them how he saved her life, and Sue wants to find the helicopter pilot who rescued her from near-certain death.
Join NOVA and a team of volcanologists looking for an elusive volcanic mega-eruption that plunged the medieval earth into a deep freeze. Investigate the geologic evidence from Greenland all the way to Antarctica to identify the 750-year-old culprit.
